Abstract

A method of making an electrochemical cell, and an electrode stack made thereby. The method includes fabrication of a coating onto selected areas of the ends of the stack by a thermal spray coating process in which the coating is applied to one of the electrodes in the stack without the coating contacting the alternate edges of the other electrode in the stack. Suitable conductive strips, compatible with the substrate materials that make up the electrodes of the cell, can be attached to the thermally sprayed coating layers, or can be embedded into the sprayed materials as they are applied to the electrode stack.
